SQLSTATE[HY000] [2002] Connection refused within Laravel homestead

问题

Using Mac OS X and Homestead 2.2.1 with Laravel 5.2.

In terminal (within homestead in my project folder) I can do php artisan to see all the available commands. When I try to run php artisan migrate I get a connection error:
SQLSTATE[HY000] [2002] Connection refused

I have setup a Laravel project with these .env settings

DB_HOST=127.0.0.1
DB_DATABASE=tcv
DB_USERNAME=homestead
DB_PASSWORD=secret

I have also tried localhost for DB_HOST and root for DB_USERNAME and DB_PASSWORD. And all possible variations of these put together!

In Sequel Pro (db management application) I CAN connect with these settings

Host       127.0.0.1
Username   homestead
Password   secret
Database   tcv
Port       33060

But this database is obviously empty, because I cant migrate to it from terminal ...

As far as I can make out it is a configuration issue, since I can connect to it with Sequel Pro. But I have honestly no freaking idea what is setup wrong.

Thanks for the help !!

EDIT
For some reason I get the same SQLSTATE[HY000] [2002] Connection refused error when moving my project to MAMP and running php artisan migrate.
Now I am completely lost ...

I just ran into this and found that changing this in the .env file from 127.0.0.1 to localhost fixed it.

DB_HOST=localhost

Problem

In Laravel you have config/database.php where all the setup for the connection is located. You also have a .env file in the root directory in your project (which everyone uses for timesaving). This contains variables that you can use for the entire project.

On a standard L5 project the MySql section of config/database.php looks like this:

    'mysql' => [
        'driver'    => 'mysql',
        'host'      => env('DB_HOST', 'localhost'),
        'database'  => env('DB_DATABASE', 'forge'),
        'username'  => env('DB_USERNAME', 'forge'),
        'password'  => env('DB_PASSWORD', ''),
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => '',
        'strict'    => false,
        'engine'    => null,
    ],

Notice there is no port set!

Although in my .env file I had set DB_PORT=33060. But that value (3306) was never read into the config/database.php.
So don't be a dumbass like myself and forget to check the database.php file.

FIX
Simply add 'port' => env('DB_PORT', 3306), to your config/database.php and set that value in .env like this DB_PORT=33060

回答3:

If you are using MAMP on a mac OS add the following line to your mysql database config file

'unix_socket' => env('DB_SOCKET', ''),

and on your .env file add

DB_SOCKET=/Applications/MAMP/tmp/mysql/mysql.sock

回答4:

Use localhost instead of 127.0.0.1 (in your .env file), then run command:

php artisan config:cache

回答5:

Another solution for anyone else who has a problem. I had all the settings correct but for some reason my changes weren't updated. Laravel actually caches the config file (which I find completely stupid).

Here was my solution after updating the configs:

php artisan config:clear

回答6:

I was having this problem. When connecting with Sequel Pro, I need to use 33060 as the port, but in the .env file it has to be 3306. I had 33060 in the .env file. Changed it to 3306 and it worked.

回答7:

This is a simple fix. Your mysql database has lost its connection to the server. If you are running a local server run this in your terminal:

mysqld

That will reconnect your database. Then (if you are using homebrew) run:

brew services start mysql

This will automatically connect your database on login.

回答8:

I had the same problem, try this works

DB_HOST=localhost

回答9:

In my case this error appeared out of blue. While staring at that mysterious error I've realized, that I was trying to run the command outside of vm...

回答10:

It's possible that your mysql hasn't started or is not to the port 3306

回答11:

After you put all configuration on .env file, if you already run php artisan serve, RESTART IT.

回答12:

Problem Fixed *

I had the same problem and fixed just by converting DB_HOST constant in the .env File FROM 127.0.0.1 into localhost DB_HOST = localhost.

No need to change anything into config/database.php

回答13:

Me, Im using vagrant, yet im executing php artisan outside the box so basically it doesn't have permission

回答14:

For me enclosing the credentials in quotes did the trick

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE='zzz'
DB_USERNAME='yyy'
DB_PASSWORD='XXX'

回答15:

If you are using Homestead then you should be running it with the default mysql port. So instead of using DB_PORT=33060, you should be using DB_PORT=3306 in your .env file. Also, remember to run your php artisan migrate commands in your homestead installation and everything should be ok.

Hope that helps.

回答16:

The only thing that solved it for me was to put the connection details in config/database.php instead of the .env file. Hope this helps

回答17:

I had a similar problem and no suggestions placed here helped me. This what has fixed my problem was to set the application name and database hostname with the same value. In my case, 127.0.0.1 works correctly.

APP_URL=127.0.0.1

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=zzz
DB_USERNAME=yyy
DB_PASSWORD=XXX

回答18:

Okay update it seems the host is not the issue but actually the port.

So its actually the port 3306 for the browser testing and yet for terminal and Sequel Pro 33060. Could it have something to do with adding it in the Homestead.yaml and set it here?

On reading the setup in relation to Laravel it says:

MySQL: 33060 → Forwards To 3306

回答19:

I could be because you might have not restarted PHP artisan since long

So After making DB changes and config:clear Tinker works fine

But to make browser refect the new DB connection you need to re-run

php artisan serve

回答20:

terminate sqld from task manager
stop MySQL from xampp control panel and restart it

if it still throw the same problem, from root folder run

php artisan cache:clear
php artisan config:cache
php artisan serve

if you still have the problem, check whether you are using multiple copies of sql server, for example through Ubuntu app, if so stop the MySQL server in ubuntu

sudo service MySQL stop

回答21:

I encountered

SQLSTATE[HY000] [2002] Connection refused (SQL: select * from projects)

The cause was that I had not started the MySQL server.

It may help to check that the MySQL is running as the first step in troubleshooting the error.

回答22:

DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=8080
DB_DATABASE=flap_safety
DB_USERNAME=root
DB_PASSWORD=mysql

the above given is my .env

    'mysql' => [
        'driver' => 'mysql',
        'url' => env('DATABASE_URL'),
        'host' => env('DB_HOST', 'mysql'),
       // 'port' => env('DB_PORT', '8080'),
        'database' => env('DB_DATABASE', 'forge'),
        'username' => env('DB_USERNAME', 'forge'),
        'password' => env('DB_PASSWORD', 'mysql'),
        'unix_socket' => env('DB_SOCKET', ''),
        'charset' => 'utf8mb4',
        'collation' => 'utf8mb4_unicode_ci',
        'prefix' => '',
        'prefix_indexes' => true,
        'strict' => true,
        'engine' => null,
        'options' => extension_loaded('pdo_mysql') ? array_filter([
            PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
        ]) : [],
    ],

the above given is my database.php file. i just commented out port from database.php and it worked for me.

回答23:

I found that my server just needed to be restarted and "bam" it was fixed.

回答24:

In my case, I was having the same error using docker and the trick was in setting in the .env file this DB_HOST=db where db is the name of the container running the database server.
